天気予測部４０１は、所定時間後の天気の予測を示す天気情報を、例えば、インターネットなどの通信回線ＮＷを介して、天気情報を提供する企業のデータベースＤＢなどから取得する。所定時間後とは、例えば、１時間後、３０分後、１０分後、５分後などである。   The weather prediction unit 401 acquires weather information indicating prediction of weather after a predetermined time from, for example, a database DB of a company providing weather information via a communication line NW such as the Internet. After the predetermined time is, for example, after one hour, after 30 minutes, after 10 minutes, after 5 minutes, or the like.

発電量予測部４０２は、天気予測部４０１が取得した天気情報に基づいて所定時間後の第１電力供給装置２０の発電量を予測する。具体的には、発電量予測部４０２は、例えば、天気に応じた光量など、天気予測部４０１が取得した天気と発電量の過去の実績などに基づいて所定時間後の第１電力供給装置２０の発電量を予測する。   The power generation amount prediction unit 402 predicts the power generation amount of the first power supply device 20 after a predetermined time based on the weather information acquired by the weather prediction unit 401. Specifically, the power generation amount prediction unit 402 determines, for example, the first power supply device 20 after a predetermined time based on the weather acquired by the weather prediction unit 401, such as the light amount according to the weather, and the past results of the power generation amount. Predict the amount of electricity generated by

需要特定部４０３は、所定時間後の電力需要を特定する。例えば、需要特定部４０３は、気温に応じたエアコンの稼働など、天気予測部４０１が取得した天気と電力消費量の過去の実績に基づいて、所定時間後の電力需要を特定する。
供給量取得部４０４は、通常時に、所定時間後に負荷１０に供給される電力が不足すると予測した場合、所定時間後に供給可能な最大電力供給可能量のリクエストを発電事業者側コンピュータ５０に送信する。このとき、供給量取得部４０４は、所定時間後に供給可能な最大電力供給可能量のリクエストとともに、供給される電力が増加した分の料金についての情報を同時に送信する。そして、供給量取得部４０４は、発電事業者から所定時間後の最大電力供給可能量を取得する。 The demand identifying unit 403 identifies the power demand after a predetermined time. For example, the demand identifying unit 403 identifies the power demand after a predetermined time based on the weather acquired by the weather predicting unit 401 and the past results of the power consumption, such as the operation of an air conditioner according to the temperature.
The supply amount acquiring unit 404 normally transmits, to the power generation company computer 50, a request for the maximum available power that can be supplied after a predetermined time, when it is predicted that the power supplied to the load 10 is insufficient after the predetermined time. . At this time, the supply amount acquisition unit 404 simultaneously transmits information on the charge for the amount of increase in the supplied power, together with the request for the maximum available power that can be supplied after a predetermined time. Then, the supply amount acquisition unit 404 acquires the maximum available power supply amount after a predetermined time from the power generation company.

不足判定部４０５は、所定時間後の電力需要が所定時間後の最大電力供給可能量よりも多いか否かを判定する。
次に、不足量算出部４０６は、所定時間後の電力需要が所定時間後の最大電力供給可能量よりも多い場合、所定時間後の電力需要と、所定時間後の第１電力供給装置２０の発電量及び所定時間後の最大電力供給可能量の総和との差分を不足電力量として算出する。 The shortage determination unit 405 determines whether the power demand after a predetermined time is larger than the maximum power supply available amount after the predetermined time.
Next, when the power demand after a predetermined time is greater than the maximum power supply available after a predetermined time, the shortage calculation unit 406 determines the power demand after the predetermined time and the power demand of the first power supply device 20 after the predetermined time. The difference between the amount of power generation and the sum of the maximum power supplyable amount after a predetermined time is calculated as the amount of insufficient power.

デマンドレスポンス部４０７は、受けた最大電力供給可能量が負荷１０に必要な電力量に対して不足している場合、各消費者にデマンドレスポンス（電力不足時に消費電力量を抑制を依頼するとともにインセンティブを与えること）の要求を送信する。   The demand response unit 407 requests each consumer to demand response (requires suppression of the amount of power consumption when power is insufficient, and the incentive when the received maximum amount of available power is insufficient with respect to the amount of power necessary for the load 10). Send request).

発電事業者側コンピュータ５０は、系統運用者側コンピュータ４０から送信された不足電力量分の電力量を発電するか否かを判定し、判定結果を系統運用者側コンピュータ４０に送信するコンピュータである。
発電事業者側コンピュータ５０は、図３に示すように、リクエスト取得部５０１、供給量特定部５０２、供給量通知部５０３を備える。
リクエスト取得部５０１は、系統運用者から所定時間後の最大電力供給可能量のリクエストを取得する。 The power generation company computer 50 is a computer that determines whether or not to generate the amount of power for the insufficient power amount transmitted from the system operator computer 40, and transmits the determination result to the system operator computer 40. .
As illustrated in FIG. 3, the power generation company computer 50 includes a request acquisition unit 501, a supply amount identification unit 502, and a supply amount notification unit 503.
The request acquisition unit 501 acquires, from the system operator, a request for the maximum available power supply amount after a predetermined time.

供給量特定部５０２は、所定時間後の最大電力供給可能量を算出する。
具体的には、供給量特定部５０２は、発電量を増加させた場合に第２電力供給装置３０の余寿命がどの程度低下するかを算出し、その余寿命の低下に伴うメンテナンスの回数が増加する場合や、定期点検期間にその余寿命の低下に伴うメンテナンスを行うことができる場合などの費用（例えば、部品交換に伴う費用の増加、部品交換に伴う運転機会の低減に伴う収益の減少など）を算出する。また、供給量特定部５０２は、発電量を増加させた場合にその増加分の発電量によりいくらの利益が得られるかを算出する。供給量特定部５０２は、この利益の算出を発電可能な発電量を上限とする複数の発電量に対して行う。そして、供給量特定部５０２は、例えば、利益がメンテナンス費用による損失よりも多くなる発電量のうち、例えば、最大の利益が得られる電力量を最大電力供給可能量とする。なお、供給量特定部５０２は、利益がメンテナンス費用による損失よりも多くなる発電量が存在しない場合には、所定時間後の最大電力供給可能量として現在の電力供給可能量（本発明の一実施形態の場合、ゼロ）を算出する。 The supply amount specifying unit 502 calculates the maximum power supplyable amount after a predetermined time.
Specifically, the supply amount specifying unit 502 calculates how much the remaining life of the second power supply device 30 is reduced when the power generation amount is increased, and the number of times of maintenance due to the reduction of the remaining life is Expenses such as increase, or maintenance that can be performed during the regular inspection period due to the decrease of the remaining life (for example, increase of cost due to parts replacement, decrease of profit due to reduction of operation opportunity due to parts replacement) Etc). Further, when the power generation amount is increased, the supply amount specifying unit 502 calculates how much profit can be obtained by the power generation amount of the increase. The supply amount specifying unit 502 performs the calculation of the profit for a plurality of power generation amounts up to the power generation amount capable of generating power. Then, the supply amount identifying unit 502 sets, for example, the amount of power that can obtain the maximum benefit as the maximum amount of power that can be supplied, out of the amount of power generation where the benefit is greater than the loss due to the maintenance cost. In the case where there is no power generation amount such that the profit is greater than the loss due to the maintenance cost, the supply amount specifying unit 502 sets the current power supply possible amount as the maximum power supply possible amount after a predetermined time. In the case of form, calculate zero).

供給量通知部５０３は、供給量特定部５０２が算出した所定時間後の最大電力供給可能量を、系統運用者側コンピュータ４０に送信することによって系統運用者に通知する。   The supply amount notifying unit 503 notifies the system operator by transmitting the maximum power supply available amount after the predetermined time calculated by the supply amount identifying unit 502 to the system operator computer 40.

次に、本発明の一実施形態による電力システム１の処理について図４を用いて説明する。   Next, processing of the power system 1 according to an embodiment of the present invention will be described with reference to FIG.

天気予測部４０１は、所定時間後の天気の予測を示す天気情報を、例えば、インターネットなどの通信回線ＮＷを介して、天気情報を提供する企業のデータベースＤＢなどから取得する（ステップＳ１）。
発電量予測部４０２は、天気予測部４０１が取得した天気情報に基づいて所定時間後の第１電力供給装置２０の発電量を予測する（ステップＳ２）。
需要特定部４０３は、所定時間後の電力需要を特定する（ステップＳ３）。 The weather prediction unit 401 acquires weather information indicating prediction of weather after a predetermined time from, for example, a database DB of a company providing weather information via a communication line NW such as the Internet (step S1).
The power generation amount prediction unit 402 predicts the power generation amount of the first power supply device 20 after a predetermined time based on the weather information acquired by the weather prediction unit 401 (step S2).
The demand identifying unit 403 identifies the power demand after a predetermined time (step S3).

供給量取得部４０４は、通常時に、所定時間後に負荷１０に供給される電力が不足するか否かを予測する（ステップＳ４）。具体的には、供給量取得部４０４は、発電量予測部４０２が予測した所定時間後の発電量が需要特定部４０３が特定した所定時間後の電力需要よりも少ない場合に、所定時間後に負荷１０に供給される電力が不足すると判定する。また、供給量取得部４０４は、発電量予測部４０２が予測した所定時間後の発電量が所定時間後の電力需要よりも多い場合に、所定時間後に負荷１０に供給される電力は充分であると判定する。   The supply amount acquiring unit 404 normally predicts whether or not the power supplied to the load 10 will be insufficient after a predetermined time (step S4). Specifically, when the power generation amount after the predetermined time predicted by the power generation amount prediction unit 402 is smaller than the power demand after the predetermined time specified by the demand identification unit 403, the supply amount acquiring unit 404 loads the predetermined time after the predetermined time. It is determined that the power supplied to 10 is insufficient. Further, when the power generation amount after the predetermined time predicted by the power generation amount prediction unit 402 is larger than the power demand after the predetermined time, the supply amount acquiring unit 404 has sufficient power to be supplied to the load 10 after the predetermined time. It is determined that

供給量取得部４０４は、通常時に、所定時間後に負荷１０に供給される電力が充分であると予測した場合（ステップＳ４においてＮＯ）、ステップＳ１の処理に戻す。
また、供給量取得部４０４は、通常時に、所定時間後に負荷１０に供給される電力が不足すると予測した場合（ステップＳ４においてＹＥＳ）、所定時間後に供給可能な最大電力供給可能量のリクエストを発電事業者側コンピュータ５０に送信する（ステップＳ５）。このとき、供給量取得部４０４は、所定時間後に供給可能な最大電力供給可能量のリクエストとともに、供給される電力が増加した分の料金についての情報を同時に送信する。 When the supply amount acquiring unit 404 normally predicts that the power supplied to the load 10 after a predetermined time is sufficient (NO in step S4), the process returns to step S1.
In addition, when the supply amount acquiring unit 404 normally predicts that the power supplied to the load 10 is insufficient after a predetermined time (YES in step S4), the power generation request for the maximum electric power that can be supplied after the predetermined time is generated. It transmits to the enterprise computer 50 (step S5). At this time, the supply amount acquisition unit 404 simultaneously transmits information on the charge for the amount of increase in the supplied power, together with the request for the maximum available power that can be supplied after a predetermined time.

リクエスト取得部５０１は、系統運用者側コンピュータ４０から所定時間後に供給可能な最大電力供給可能量の問い合わせ（所定時間後の最大電力供給可能量のリクエスト）を受信する（ステップＳ６）。
供給量特定部５０２は、所定時間後の最大電力供給可能量を算出する（ステップＳ７）。
供給量通知部５０３は、供給量特定部５０２が算出した所定時間後の最大電力供給可能量を、系統運用者側コンピュータ４０に送信する（ステップＳ８）。 The request acquisition unit 501 receives from the system operator computer 40 an inquiry about the maximum available power that can be supplied after a predetermined time (a request for the maximum available power after a predetermined time) (step S6).
The supply amount specifying unit 502 calculates the maximum possible power supply amount after a predetermined time (step S7).
The supply amount notification unit 503 transmits the maximum power supplyable amount after the predetermined time calculated by the supply amount specification unit 502 to the system operator computer 40 (step S8).

供給量取得部４０４は、発電事業者から所定時間後の最大電力供給可能量を受信する（ステップＳ９）。なお、供給量取得部４０４は、受信した最大電力供給可能量の総和が実際に必要な電力量を超えた場合には、例えば、回答の早い順（受信順）、電力料金の安い順などの優先順位を決めて、必要な電力量を得ればよい。   The supply amount acquisition unit 404 receives the maximum available power supply amount after a predetermined time from the power generation company (step S9). In addition, when the total of the received maximum available power amounts actually exceeds the required power amount, the supply amount acquiring unit 404 may, for example, order of earlier answers (reception order), such as the order of low power rates, etc. You can decide the priority and get the necessary amount of power.

不足判定部４０５は、所定時間後の電力需要が所定時間後の最大電力供給可能量よりも多いか否かを判定する（ステップＳ１０）。具体的には、不足判定部４０５は、需要特定部４０３が特定した所定時間後の電力需要が供給量特定部５０２が算出した所定時間後の最大電力供給可能量以下であると判定した場合（ステップＳ１０においてＮＯ）、所定時間後に負荷１０に供給される電力は充分であると判定し、ステップＳ１の処理に戻す。
また、不足判定部４０５が、需要特定部４０３が特定した所定時間後の電力需要が供給量特定部５０２が算出した所定時間後の最大電力供給可能量よりも多いと判定した場合（ステップＳ１０においてＹＥＳ）、不足量算出部４０６は、所定時間後の電力需要と、所定時間後の第１電力供給装置２０の発電量及び所定時間後の最大電力供給可能量の総和との差分を不足電力量として算出する（ステップＳ１１）。 The shortage determination unit 405 determines whether or not the power demand after a predetermined time is larger than the maximum available power supply amount after a predetermined time (step S10). Specifically, when the shortage determination unit 405 determines that the power demand after the predetermined time specified by the demand identification unit 403 is equal to or less than the maximum possible power supply amount after the predetermined time calculated by the supply amount identification unit 502 ( It is determined in step S10 that the power supplied to the load 10 after a predetermined time is sufficient, and the process returns to step S1.
In addition, when the shortage determining unit 405 determines that the power demand after the predetermined time specified by the demand identifying unit 403 is larger than the maximum possible power supply amount after the predetermined time calculated by the supply amount identifying unit 502 (in step S10) YES), the shortage calculation unit 406 calculates the difference between the power demand after a predetermined time and the sum of the power generation amount of the first power supply device 20 after a predetermined time and the maximum power supply available after a predetermined time It calculates as (step S11).

デマンドレスポンス部４０７は、不足量算出部４０６が算出した不足電力量に基づいて、デマンドレスポンスを要求、すなわち負荷１０の低減量と、その負荷１０の低減を行った場合に得られるインセンティブとを消費者に通知する（ステップＳ１２）。
デマンドレスポンスの要求の通知を受けた消費者は、そのデマンドレスポンスの要求を受け入れるか否かを判定し、すなわち、負荷１０を低減しインセンティブを得るか否かを判定する。そして、消費者は、判定結果に応じた処理を行う。 The demand response unit 407 requests a demand response based on the amount of power shortage calculated by the shortage amount calculation unit 406, that is, the amount of reduction of the load 10 and the incentive obtained when the load 10 is reduced. Are notified (step S12).
The consumer notified of the demand response request determines whether to accept the demand response request, that is, determines whether to reduce the load 10 and obtain an incentive. And a consumer performs processing according to a decision result.

以上、本発明の一実施形態による電力システム１について説明した。

In addition, the power system 1 including the power generation company computer 50 can accurately specify the maximum power supply capacity.
In addition, the power system 1 including the system operator computer 40 and the power generation company computer 50 appropriately sets the demand response (restricting the power consumption at the time of power shortage) to each consumer based on the power shortage. The amount of available power can be determined by the respective gains and losses of the system operator and the power producer.

なお、本発明の一実施形態では、第１電力供給装置２０は、消費者及び系統運用者の少なくとも何れか一方が所持する装置であるものとして説明した。しかしながら、本発明の別の実施形態では、第１電力供給装置２０は、発電事業者が所持する装置であってもよい。   In the embodiment of the present invention, the first power supply apparatus 20 is described as an apparatus owned by at least one of the consumer and the system operator. However, in another embodiment of the present invention, the first power supply device 20 may be a device owned by a power producer.

なお、本発明の一実施形態では、第２電力供給装置３０は、通常時に、負荷１０に対して所定の電力を供給可能な装置であり、所定の電力を基準に負荷１０に供給する電力を増減できる装置であってよい。また、本発明の別の実施形態では、第２電力供給装置３０は、通常時に、負荷１０に対してまったく電力を供給しない装置であり、負荷１０に電力を供給しないか、電力を供給しその供給量を増減できる装置であってもよい。   In the embodiment of the present invention, the second power supply device 30 is a device capable of supplying predetermined power to the load 10 at normal times, and supplies power to the load 10 based on the predetermined power. It may be an apparatus that can be increased or decreased. Moreover, in another embodiment of the present invention, the second power supply device 30 is a device that does not supply power to the load 10 at all times, and supplies power to the load 10 or supplies power. It may be an apparatus capable of increasing or decreasing the supply amount.

なお、本発明の一実施形態では、第２電力供給装置３０は、例えば、火力発電などの化石燃料を利用して発電した電力を供給する装置であるものとして説明した。しかしながら、本発明の別の実施形態では、第２電力供給装置３０は、例えば、太陽光エネルギー、風力エネルギー、水力エネルギーなどの再生エネルギーを利用して発電した電力を供給する装置を含むものであってもよい。第２電力供給装置３０が、太陽光エネルギー、風力エネルギー、水力エネルギーなどの再生エネルギーを利用して発電した電力を供給する装置である場合には、発電事業者側コンピュータ５０は、天気に基づいて発電量を予測するものであってよい。   In the embodiment of the present invention, the second power supply device 30 is described as a device that supplies power generated using fossil fuel such as thermal power generation, for example. However, in another embodiment of the present invention, the second power supply device 30 includes a device that supplies power generated using regenerated energy such as, for example, solar energy, wind energy, or hydro energy. May be If the second power supply device 30 is a device that supplies power generated by using regenerated energy such as solar energy, wind energy, or hydro energy, the power generation company computer 50 is based on the weather. The amount of power generation may be predicted.

なお、本発明の一実施形態では、供給量取得部４０４が所定時間後に供給可能な最大電力供給可能量のリクエストとともに、供給される電力が増加した分の料金についての情報を発電事業者側コンピュータ５０に送信するものとして説明した。しかしながら、本発明の別の実施形態では、発電事業者側コンピュータ５０（例えば、供給量通知部５０３）が供給される電力が増加した分の料金を提示し、提示した料金を条件に最大電力供給可能量を系統運用者側コンピュータ４０に送信するものであってもよい。   In one embodiment of the present invention, the power generation company computer is provided with a request for the maximum available power that can be supplied after a predetermined time by the supply acquisition unit 404, as well as information on charges for the increased amount of power supplied. It was described as sending to 50. However, in another embodiment of the present invention, the power generation company computer 50 (for example, the supply amount notification unit 503) presents a charge for the increased amount of power supplied, and the maximum power supply is provided on the condition of the presented charge. The possible amount may be transmitted to the system operator computer 40.

なお、ここでの発電事業者側コンピュータ５０は、１つの発電事業者側コンピュータ５０に限定するものではなく、複数の電力事業者それぞれが所持する発電事業者側コンピュータ５０であってよい。送信先の発電事業者側コンピュータ５０が複数ある場合には、供給量取得部４０４は、所定時間後に供給可能な最大電力供給可能量のリクエストを送信するとともに、供給される電力が増加した分の料金については入札を行う旨を同時に送信するものであってもよい。供給量取得部４０４は、入札を行う場合には、例えば、入札対象となる発電量とその発電量に対する単位電力当たりの料金（一般的な入札の最低落札価格に相当）とを提示する。   The power generation company computer 50 here is not limited to one power generation company computer 50, and may be a power generation company computer 50 owned by each of a plurality of power companies. When there are a plurality of power generation enterpriser computers 50 of the transmission destination, the supply amount acquisition unit 404 transmits a request for the maximum available power that can be supplied after a predetermined time, and the amount of supplied power has increased. With regard to the fee, it may be transmitted simultaneously to bid. When making a bid, the supply amount acquiring unit 404 presents, for example, a power generation amount to be bid and a charge per unit power for the power generation amount (corresponding to a minimum bid price of a general bid).

なお、発電事業者は、当初の契約範囲内の供給可能な電力量である場合であっても、負荷１０とは異なる負荷への電力供給量が既に増加しており、負荷１０に対する供給電力を増加させることができない場合がある。この場合、デマンドレスポンス部４０７は、系統運用者に対してデマンドレスポンスの要求、すなわち、契約電力内であるがこれ以上の供給電力の増加を行わない代わりにその分のインセンティブを与えることを系統運用者側コンピュータ４０に要求するものであってもよい。   Note that the power producer has already increased the amount of power supplied to a load different from the load 10, even if the amount of power that can be supplied within the initial contract range, It may not be possible to increase it. In this case, the demand response unit 407 performs a system operation of requesting the system operator for a demand response, that is, providing an incentive for the demand power within the contracted power but not increasing the supplied power more than that. It may be required for the computer 40 on the other side.
